squid最多支持cache多少個object？

killua

有沒有人研究過這個問題？目前我cache3000多萬個object，出現(xiàn)squid進(jìn)程自動重啟了

具體的錯誤是

1. FATAL: xcalloc: Unable to allocate 1 blocks of 1048640 bytes!
   
2. 
   
3. Squid Cache (Version 2.6.STABLE20): Terminated abnormally.
   
4. CPU Usage: 49892.603 seconds = 43028.331 user + 6864.272 sys

復(fù)制代碼

我的存儲方式是COSS

查了squid的FAQ，好像并不能解決我的問題

http://man.chinaunix.net/newsoft/squid/Squid_FAQ/FAQ-8.html#ss8.7 雖然有xmalloc: Unable to allocate的解釋

Messages like "FATAL: xcalloc: Unable to allocate 4096 blocks of 1 bytes!" appear when Squid can't allocate more memory, and on most operating systems (inclusive BSD) there are only two possible reasons:

The machine is out of swap
The process' maximum data segment size has been reached



附上我的內(nèi)存信息

1. # free
   
2.              total       used       free     shared    buffers     cached
   
3. Mem:       8161516    8119484      42032          0      82800    3760492

5. Swap:      2096472        208    2096264
